     * `IO.select` accepts +Float::INFINITY+ as a timeout argument.

+    * `Ractor::Port` class was added for a new synchronization mechanism
+      to communicate between Ractors. [[Feature #21262]]
+
+        ```ruby
+        port1 = Ractor::Port.new
+        port2 = Ractor::Port.new
+        Ractor.new port1, port2 do |port1, port2|

+
+        `Ractor::Port` provides the following methods:
+
+        * `Ractor::Port#receive`
+        * `Ractor::Port#send` (or `Ractor::Port#<<`)
+        * `Ractor::Port#close`
+        * `Ractor::Port#closed?`
+
+        As result, `Ractor.yield` and `Ractor#take` were removed.
+
+    * `Ractor#join` and `Ractor#value` were added to wait for the
+      termination of a Ractor. These are similar to `Thread#join`
+      and `Thread#value`.
+
+    * `Ractor#monitor` and `Ractor#unmonitor` were added as low-level
+      interfaces used internally to implement `Ractor#join`.
+
+    * `Ractor.select` now only accepts Ractors and Ports. If Ractors are given,
+      it returns when a Ractor terminates.
+
+    * `Ractor#default_port` was added. Each `Ractor` has a default port,
+      which is used by `Ractor.send`, `Ractor.receive`.
+
+    * `Ractor#close_incoming` and `Ractor#close_outgoing` were removed.
+
 * Set
 
     * Set is now a core class, instead of an autoloaded stdlib class.
